Maintaining performance during vaccination periods: new data with i-BOOST
Infectious bronchitis is one of the main respiratory diseases encountered in poultry farming. Of viral or bacterial origin, it manifests itself through persistent coughing, abundant secretions, and sometimes fever. If not properly controlled, it can have a lasting impact on animal performance and lead to more severe complications.
In poultry farming, vaccination periods are often associated with a decline in zootechnical performance. Stress, loss of appetite, slowed growth… These are all side effects that can impact the profitability of the farm.
To address this issue, Biodevas Laboratories conducted a field test in the Netherlands at a veterinary partner’s facility on slow-growing chickens (stocking density: 26 kg/m² – slaughter on day 56).
The objective: to evaluate the effect of i-BOOST on zootechnical performance during the vaccination period.
Test protocol:
| Vaccinations administered | Treatment |
| D0 and D7: Infectious bronchitis D14: Newcastle disease D25: Gumboro disease | Control group: No supplement i-BOOST group: 1 ml/L for 2 days after each vaccination |
Results:
The data collected showed a positive effect of i-BOOST:
• Improvement in FCI
• Higher live weight at the end of the rearing period
These results confirm the value of targeted support at the time of vaccination to maintain performance while limiting the impact of vaccination stress.
